Description
Zum Drehen und Hobeln sind scheibenförmige spanabhebende Werkzeuge bekannt; diese Scheibenstähle sind ihrer Schnittwirkung und Schneidenform nach von den gewohnlichen Stählen nicht verschieden, bieten jedoch bei der Herstellung Vorteile vor jenen. Das Werkzeug gemäß der Erfindung besteht in einer aus einem Kegelstumpf herausgeschnittenen Scheibe, die in besonderer, aus derDisc-shaped cutting tools are known for turning and planing; These disc steels differ from the usual ones in terms of their cutting action and cutting edge shape Steels are no different, but offer advantages over those in manufacturing. The tool according to the invention consists in one cut out of a truncated cone Disc that in particular, from the
ίο Zeichnung ersichtlicher Weise angeordnet werden muß.ίο the drawing can be arranged in an obvious manner got to.
In der Zeichnung ist die Erfindung dargestellt. Die Abb. ι und 2 zeigen das Werkzeug beim Drehen. Abb. ι ist die Ansicht von der Supportseite bei einer gewöhnlichen Drehbank, in der Pfeilrichtung B gesehen, Abb. 2 ist die Ansicht von der Antriebsseite, entsprechend Pfeilrichtung A. The invention is shown in the drawing. Fig. Ι and 2 show the tool when turning. Fig. Ι is the view from the support side of an ordinary lathe, seen in the direction of arrow B , Fig. 2 is the view from the drive side, according to the direction of arrow A.
Das scheibenförmige, durch Schleifen der Boden- oder Mantelfläche geschärfte Werkzeug α wird durch eine nicht gezeichnete Einspannvorrichtung, deren Form vom Verwendungszweck und von der Maschinenart abhängt, derart in den Support eingespannt, daß die Achse C-C seines Ursprungskegels mit der Drehachse B-B des Werkstückes b bei wagerechter Beobachtung, also in Pfeilrichtung B, einen bestimmten Winkel α bildet, wobei die Spitze des Ursprungskegels in an sich bekannter Weise in der Vorschubrichtung des Stahlhalters liegt. Nach Anstellung des Stahles wirkt der Teil c-e der scharfen Kante als Schneide. Der entstehende Span ist mit f bezeichnet, während d die Spantiefe angibt. Für die Einspannung des Werkzeugs hinsichtlich der Höhe zur Werkstückachse gelten wesentlich andere Gesichtspunkte als beim Bekannten. So wird das Werkzeug in den wenigsten Fällen auf Mitte eingestellt; vielmehr ist oft Über- oder Unterhöhung geboten. . The disk-shaped tool α , sharpened by grinding the bottom or outer surface, is clamped into the support by a clamping device, not shown, the shape of which depends on the intended use and the type of machine, so that the axis CC of its cone of origin coincides with the axis of rotation BB of the workpiece b horizontal observation, that is, in the direction of arrow B, forms a certain angle α, the tip of the cone of origin lying in a manner known per se in the direction of advance of the steel holder. After adjusting the steel, the part ce of the sharp edge acts as a cutting edge. The resulting chip is denoted by f , while d indicates the depth of cut. For the clamping of the tool with regard to the height to the workpiece axis, significantly different aspects apply than with the known. The tool is rarely set to the center; rather, it is often necessary to over- or under-elevate. .
Wegen der ebenen Grundfläche 0-0 des Schneidwerkzeuges muß es geneigt (Winkel α) eingestellt werden.Because of the flat base area 0-0 of the cutting tool, it must be set at an incline (angle α).
Das Werkzeug bietet dem Bekannten gegenüber folgende Vorteile: Geringerer Kraftbedarf, einfachere genaue Herstellung, längere Schneidhaltigkeit, ruhigerer Schnitt ohne Rattermarken, Benutzung desselben Stahles zum Schruppen und Schlichten, wobei es gleichzeitig zum Drehen und Hobeln geeignet ist. 5c1 The tool offers the following advantages over the known: Less power requirement, easier precise production, longer edge retention, smoother cut without chatter marks, use of the same steel for roughing and finishing, whereby it is also suitable for turning and planing. 5c 1
Die Fläche 0-0 kann aus einer Auflage von Schnelldrehstahl bestehen. In besonderen Fällen kann man das Werkzeug sich beim Arbeiten drehen lassen, wobei als Antriebskraft der Schnittdruck dienen kann. Auch kann man mit einem einzigen Werkzeug, lediglich durch Drehen der Einspannvorrichtung bei Vor- und Rückwärtsgang, schneiden.The surface 0-0 can consist of a layer of high-speed steel. In special cases, the tool can be turned while working, whereby the cutting pressure can serve as the driving force. It is also possible to cut with a single tool, simply by turning the clamping device in forward and reverse gear.
